Very cool! Another application that is great for collaborative prototyping is precursor [1]

I really love Precursor, you don't need an account to get started and it's simplicity makes it really quick to throw something together.

I ran https://precursorapp.com on Vultr in the early days. I had a setup with a few dedicated servers for the DB and load balancer, and then I would spin up and shut down application servers whenever I deployed new backend code. Infrastructure looked like: https://precursor.precursorapp.com/document/Backend-Infrastructure-175…
I used to recommend it to everybody, but don't any longer. I had two negative experiences that made me stop recommending it.
The first is frequent restarts. Very small sample size, but both me and a friend started experiencing restarts every month or so. I don't think I got any advance warning about the restarts, but I'm not positive.
The second is that networking between instances stopped working for me in the middle of the night shortly after Vultr did an upgrade. Support wasn't able to help (though they did try) and I couldn't figure out anything on my end. I had to switch everything to AWS to get the site back online before people woke up in the morning.
I was super happy with it before those two problems, though, and the people there seemed competent and professional. I was also using FreeBSD, so it may not be as well supported as Linux (which may have contributed to the networking problem).

I'm a fan of https://precursorapp.com/, but will give excalidraw a go.

Precursor would be very challenging to build in ~120 lines of vanilla JS: https://precursorapp.com

I'm regularly hearing about web applications written in ClojureScript, a.k.a. Clojure (a dialect of Lisp, [1]) compiled to JavaScript. Recently I've heard of:
- https://github.com/asciinema/asciinema-player
- https://precursorapp.com/ (not open-source)

Wrong guess.
The project's repository has a list of things people built with DataScript.
One of those is https://precursorapp.com
It's highly usable, stable and fun app!

PayGarden | Full-stack | SF | Full Time | ONSITE (preferred, sponsor visa) + REMOTE (some positions)
What: With PayGarden merchants can accept major brand gift cards as payment - imagine Stripe, but instead of credit cards, your customers can pay with Starbucks, Walmart, Amazon (& 100 more) gift cards.
See our partnership with Watsi [0] turning major brand cards into life-changing healthcare for people, or Private Internet Access [1] making VPN payment anonymous.
How: Our systems handle millions of dollars, built primarily with Clojure/Script & a dash of Rust.
Us: If you've ever done any work with Clojure, you've likely seen someone from our tiny, incredibly high-leverage team of Xooglers & YC alumni. We've:
- contributed to the cljs compiler [2],
- built cool open-source Clojure/Scripts apps [3],
- given [4] dozens [5] of talks [6] on [7] fun and cutting [8] edge development
- run the #sfcljs & ReasonDojo meetups
You: Love working with others, taking ownership over business concerns while jumping into other parts of the stack to help out. An internal drive to continuously improve, while remaining humble.
